Harry Potter and the Chamber of Secrets ending explained (spoilers)

[jesse]

Tom Riddle comes to life, and he's the 16 year old Voldemort. Ginny opened the Chamber of Secrets though not of her free will as she was being possessed by Riddle (Voldemort.) Harry destroys the memory of Riddle by stabbing the basilisk tooth through the diary. Lockhart is a really a fraud and he loses his memory and ends up in St Mungo's Hospital for Magical Maladies and Injuries. Dobby belongs to Lucius Malfoy, and Harry tricks Lucius into setting Dobby free.
